What is attached to the derailleur?

Considering buying this bike. Have not seen it yet and owner is clueless. Thanks.

It looks as if someone added the clamp and spring. Who knows the reason? Possibly a spring broke or was assembled incorrectly in the Super Record derailleur and this was a PO's work around. Or a means to keep the cable and housing loop closer to the frame. These are my best guesses.

Is that some sort of external spring and homebrew mount for it? I was thinking for a moment there maybe some sort of kludge to make a Campagnolo rear derailleur work with a Simplex or Huret dropout, but the Campagnolo diver's helmet cable stop makes me think it probably has a Campagnolo rear dropout, so ... I think we all need for you to go look at it or take some pix ...

That's a new one for me. It's clamped to the stay, with what looks like a spring going down to the RD. What's the bike? It has a nice '86 un-fluted crank.

My guess is it is a generator bracket being used as a b-tension spring as the Campagnolo Super Record does not have one.

Yes, same bike. Looks like it has been for sale for a long time too. A shame it has been so neglected. Pedals and brake levers were replaced with non Campy. Thx.

Exactly. But the spring is so near the pivot that it doesn't look to be very effective.

RE: pedals
 

Actually those are Campagnolo pedals with no quills.

I have no idea what the thinking is but there IS a problem with the top jockey wheel and the chain feed. If you are interested in this bike , look it over carefully for other problems. Whatever is going on , this is not a conventional fix.

Who cares what it does? It has no bearing relevant to purchase. You are going to remove it anyway.

The entire bike smells. My guess its stolen. Who buys a Richard Sachs, even used that would do such atrocity? Or they're so piss poor after $pending for it, they then resort to butchery.

And a prior owner wouldn't do such. Just when you think to have seen it all, should also second guess why the OP would even openly question this online. Really? C'mon, even if were mysterious did he not finger his google for some basic knowledge about a Campagnolo derailleurs or the makers name on the bike? Morons.

Evidently...............they did.

The quills look to have been hacked off, if not, they would be the coveted pista's. ;)

Racked Up Richard Sachs to me

Depending on price and your comfort level, it doesn't matter, nothing life threatening from here IMO.

Sad that this was done to a Sachs but presents you with a rare opportunity if you can get there.

Ifn I was you and the $$$ line up, it would already be at my house. ;)

Bike has lived in the small chainring.
munched spoke protector.. Rube Goldberg at work.
bike needs a full service .
if not crashed or something up front, should be a good starting point.

I would expect a stretched chain and freewheel, hopefully intact bottom bracket bearings. Those rims have a rep for being hard to mount tires onto, tire jack to the rescue.
